Why this module exists. Data Loss Prevention is a class of controls that has evolved from naive regex-on-email into a multi-channel detection programme spanning endpoint, network, and cloud. This module covers the modern DLP architecture and the operational disciplines that distinguish effective DLP from compliance-checkbox DLP.

Why this module exists. Indian enterprises commonly buy DLP licences and never tune them effectively. The deployment runs in monitor-mode forever, alerts go to a queue nobody reads, and the same exfiltration paths remain open. This module covers what works.

The three DLP channels

Channel What it covers
Endpoint DLP USB transfers, clipboard, screen capture, file system, printing
Network DLP Web upload, email, FTP, instant messaging
Cloud DLP / CASB SaaS uploads, OAuth-app permissions, public link sharing

Modern programmes have all three; coverage gaps in any channel become the exfiltration path. Microsoft Purview, Symantec DLP, Forcepoint, Netskope are typical vendor solutions.
